"What did my son do to die like this?" he asks, crying. "What was his mistake? He is 10 or 11 months old. What did he do?"

Paul Danahar, the BBC's Middle East bureau chief, tweeted that Misharawi's neighborhood in Gaza City was not under attack when a shell came through the roof of his home and hit the room where Misharawi's son, Ahmad, was. The baby along with with Misharawi's sister-in-law died.

"[Question] asked here is: if Israel can kill a man riding on a moving motorbike (as they did last month) how did Jihad's son get killed?" Danahar said on twitter.

He adds that Israel's Deputy Foreign Minister Danny Ayalon tells the BBC that they apologize for civilian casualties, "but responsibility lies with Hamas."
